Vue d'ensemble

Description

The LT3475EFE is a dual-channel DC/DC converter designed by Linear Technology (now part of Analog Devices) for efficient power management applications. It integrates two independent switching regulators, allowing it to drive various loads with different voltage and current requirements. The device is capable of operating with input voltages ranging from 2.5V to 16V, making it versatile for battery-powered and other low to medium voltage applications.
The LT3475EFE is optimized for high efficiency and low noise, with features such as integrated power switches, an adjustable switching frequency (up to 2.5MHz), and a low dropout mode to maintain regulation even when the input voltage is close to the desired output voltage. Additionally, it includes protections like overcurrent and over-temperature shutdown, enhancing its reliability in demanding environments.
Its compact design, housed in a thermally enhanced 16-lead TSSOP package, makes it suitable for space-constrained applications such as portable devices, industrial equipment, and automotive systems. The versatility and robust performance of the LT3475EFE make it an attractive choice for designers seeking efficient, flexible power solutions.

Features

The LT3475EFE is a dual step-up DC/DC converter designed by Analog Devices (formerly Linear Technology). It features high efficiency and versatility, making it suitable for various power supply applications. Key features include:
1. Dual Channel Operation: It supports two independent converters in one package, each capable of delivering up to 1.3A output current.
2. Wide Input Voltage Range: The LT3475EFE operates with input voltages from 2.4V to 16V, accommodating various power sources.
3. High Efficiency: Efficiency can exceed 85%, depending on the configuration and load conditions.
4. Adjustable Output Voltage: It delivers adjustable output voltages, with one channel capable of generating up to 40V and the other up to 25V.
5. Internal Power Switches: Integrates internal power switches to simplify design and reduce component count.
6. Low Shutdown Current: It features a low shutdown current of less than 1µA, which conserves battery life in portable devices.
7. Frequency Synchronization: Allows synchronization to an external clock for better control over electromagnetic interference (EMI).
8. Protection Features: Includes thermal shutdown, soft-start, and current limiting to enhance reliability and safety.
These features make the LT3475EFE well-suited for applications like OLED displays, automotive electronics, and portable devices requiring efficient power conversion.

Package
